Same here. If I switch computers it will tell me I have new messages after I've already read them. Though it didn't happen on a campus computer. The same thing happens with the forum though. If I read all the new forum stuff and switch to a different computer, the forum threads will show up as never having been read.
I'm not complaining or anything, I'm just saying.
But I was wondering if Brad could possibly make the text box for the PMs bigger. Maybe about the same size as the text box for the forums. It would be much easier to write, especially longer messages.
